由于电化学反应的非均质性质,质量传递是反应和反应器开发期间的重要考虑因素。采用实验研究和计算流体力学方法研究了连续电化学反应器内不同流道几何形状对壁面与溶液间传质的影响。通道形状被示出对传质系数具有适度的影响。然而,反应溶液从电极的一侧跳到另一侧,因此在流动中间切换极性,具有最大的效果。
Due to the heterogenous nature of electrochemical reactions, mass transport is an important consideration during reaction and reactor development. The effect of different flow channel geometries on mass transfer between wall and solution within a continuous electrochemical reactor has been investigated using experimental studies and computational fluid dynamics. The channel shape is shown to have modest impact on the mass transfer coefficient. However, the reaction solution hopping from one side of an electrode to the other, so switching polarity mid-flow, has the greatest effect.
